Application filed May 10, 1922. SerialNo. 559,822.

-My invention has for its object primarily to provide .a strainerand stopper. designed to be applied to theidischarge pipe of a stationary wash tub, or sink. or other receptacle so that water or other fluidmaybe drained therefrom. as well as straining foreign material which-may be contained in the fluid to prevent the material from clogging the passageof the pipe, and which is of a form adapted to permit the entrance to the pipe to be closed when desired for accumulating a quantity of fluid inthereceptacle. The invention contemplates mainly the provision of a hollow body having an annular upstanding wall with an open top, and having on its lowerend a"perfo rated bottom. The hollow body may be of a size adapted to be removably held over the entrance of the pipe of a stationary wash tub, sink or other receptacle so that when it is desired to drain the receptacle of water or other fluid it will flow through the perforations into the body and into the pipe. Should the fluid contain foreign material it will be strained .during the flow of the fluid through the perforations, anda separate stopper element is provided for removable insertion into the body to close ingress into the pipe to allow a quantity of the fluid tobe accumulated in the receptacle.

A. further object of the invention is to provide a strainer and stopper of a simple, efficient and durable construction which may be made in any appropriate shape and size.

\Vith these and other objects in view, the invention will be hereinafter more fully described with reference to' the accompanying drawing forming a partof this specification in which similar characters of reference indicate corresponding parts in all the views, and will then be pointed out in the claims at the end of the description.

In the drawing, Figure 1 is a fragmentary view, showing atop plan of a stationary wash tub-or sink with one form of strainer and stopper embodying my invention applied thereto.

Fig.2 is an enlargedfragmentary view, showing an enlarged section taken through the'form of the device shown in Fig. 1 and which also shows section taken through part of the tub and throughpart of itsdischarge pipe, and

Fig. 3 is an, enlarged'fragmentar'y View,

showing a detail section taken on the line 3-3 of Fig. 2. i

The strainer and stopper has a hollow T body 1O with an upstanding annularwall 11, and on the lower end of this wall is a" bottom 12, while the upper end of the wall is open to provide an entrance "13,. When the device is of aform adapted to be used in a stationary wash tub or sinkor other receptacle, as 14, having a discharge pipe, as 15,-with cross-bars, as 16, provided in its mouth. the wall '11 of the hollow body 10 is made larger in diameter than the diameter o f the platefThe central part ofthe bottom 12 may then be concaved, asat17, with spacedinterstices or perforations as 18, while the edge'portion, as 19, of the bottom may be imperforate as well as being flat- Also in th annular wall 11 of the body 10 in spaced proximity to the bottom 12 may be one or more rows of perforations, as 20, and on opposite parts of the underside of; the bottom 12 are depending clips, as 21 and 22, for serving as means to removably fasten. the body to the cross-bars 16 of the pipe 15.

The clips 21 and 22 are of corresponding shapes and sizes; and each clip 7 is preferably of the form 'of a hook hav ing a shank portion 23 with an angu larly bent part or finger, as 24. These. clips or hooks are relatively arranged so that their fingers 24 are disposed in opposite directions, and both clips are of sizes so that when the body 10 isarranged over the pipe with its bottom positioned onthe crossbars 16 the fingers of the clips or hooks will engage the crossbars when the body is partially rotated accordingly. The body will thereby be detachably fastened over the pipe. When water is delivered into the receptacle 141 and drained into the pipe 15 the. water or other fluid will flow into the body through the perforations 20, and then flow through the perforations 18 of the bottom 12 into the discharge pipe 15. Foreign solid substances which may be mixed with the water will then be strained to avoid passage into the pipe which in turn will prevent clogging of the pipe.

Serving to permit the passage of the fluid into and out of the body 10 to be cut-off when desired, a stopper, as 25, is provided. The stopper 25 is in the form of a cap having a top plate 26 with a downwardly protruding annular wall 27 of a diameter adapted to be inserted in the hollow body 10 through its entrance 13 as well as removably and snugly fitting the wall 11 of the body. he wall 27 of the cap is also of a length so that when the cap is inserted in the body 10 the free edge of the cap will abut against the flat edge portion 19 of the bottom 12 of the cap so as to close the passage through the perforations 20 of the hollow body for preventing the flow of fluid into the discharge pipe through the body 10, and the stopper or cap 25 may be connected to the body by a flexible line or chain 2b having its ends attached to the body and to the cap.

In the foregoing description, I have embodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle or sacrificing any of the advantages, of. this invention, therefore, I reserve to myself the right to make such changes as fairly fall within the scolpe thereof.

aving thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. As an article of manufacture, a strainer and stopper for pipes, formed with a hollow body having an annular upstanding wall with an open top. and having perforations in spaced proximity to its lower end, a bottom onthe lower end of the annular wall, having an imperforate fiat edge portion and having a perforated concaved central portion, and hooks on the bottom of the. body for releasably engaging a crossbar in the entrance of the pipe by partially rotating the body.

2. As an article of manufacture, a strainer and stopper for pipes, formed with a hollow body having an annular upstanding wall with an open top and having perforations in spaced proximity to its lower end, a bottom on the lower end of the annular wall, having an imperforate fiat edge portion and having a perforated concaved central portion, hooks on the bottom of the body for releasablyengaginga crossbar in the entrance of the pipe. by partially rotating the body, a separate stopper element adapted to be removably fitted in the open end of the body for cutting-off ingress to the body by closing the passages of the spaced perforations in the wall of the body, and a flexible line element having its ends attached to, the

body and to the stopper element.
